  • 400 g | 14oz tin black beans drained and rinsed
  • 4 tbsp Sukrin Gold or other granulated sweetener | .5 syns per tbsp
  • 2 tbsp brown sugar 3 syns per tbsp (can replace with sweetener)
  • 3 eggs
  • 3 tbsp unsweetened cocoa powder 2.5 syns per tbsp
  • 1 tsp gluten free baking powder .5 syns
  • 1 tsp vanilla extract
  • icing sugar to dust optional
  • Fry Light to grease the tin
  • Sweet Freedom Choc Shot to drizzle (optional)


  •  Preheat the oven to 180C /350F. Spray a square brownie tin (I used a 20cm one) with Fry Light and line with baking paper, letting the paper hang over the sides.
  • Add all the ingredients to a blender or food processor and blitz until you have a smooth, fairly liquid, batter.
  • Divide between your muffin tin, filling only halfway up or pour into the prepared loaf tin. Scatter a few frozen berries over the top (they will sink into the batter slightly as the brownies bake).
  • Pour the batter into your prepared tin and bake for 30-35 minutes until risen. A skewer inserted in the centre should come out clean or with a few moist crumbs.
  • Leave to cool in the tin for 5 minutes then lift out using the paper.
  • Drizzle with Sweet Freedom Choc Shot if you are using. Dust with a little icing sugar or cocoa powder, slice and serve.



There's just under 2 Syns per brownie if made with sweetener and sugar. There's 1 sun per brownie if made just with sweetener.
There's 3 Weight Watchers SmartPoints and around 80 calories per serving.
Freezing Instructions
Cool completely, slice and wrap them in greaseproof paper and then a layer of foil (don’t add any glaze or icing sugar). Defrost at room temperature and reheat for a few seconds in the microwave before serving.
